| FORMULATIONS: |
Soluble powder, granules. |
| HAZARDS: |
Fish: LC50 >1000 ppm (rainbow trout,
bluegill). Bird: LD50 350 mg/kg (mallard); LD50 140 mg/kg
(pheasant). Bee: LC50 0:2 ¦Ìg/bee. SOIL PARTICLE ADSORPTION:
Acephate dissipates rapidly with half-lives of <3 and
7 days in aerobic and anaerobic soils, respectively. Major
metabolite was CO2 in both soil types. TLC and soil column
studies indicate acephate is mobile in most soils but
that aged residues (excluding acephate and its degradate
methamidophos) are immobile
in sandy loam soil. Apparently most of the applied acephate
and degradate methamidophos degrade to immobile compounds
in 20 days. |
